    摘要: Disclosed is a synergistic sterilizing and preserving method for fresh meat with high voltage electric field plasma and nano photocatalysis, which belongs to the technical field of cold sterilization of food package. The method comprises the steps: uniformly mixing a photocatalyst, a coupling agent and coating liquid at a high speed, performing the coupling to obtain modified coating liquid, smearing the coating liquid onto the surface of a plastic packaging film to obtain a packaging material with a photocatalytic bacteriostatic function, packaging fresh meat in an MAP (modified atmosphere packing) manner by adopting the bacteriostatic packaging material, wherein a coating containing the photocatalytic material is disposed at the inner side of a package, placing the packed fresh meat between two electrodes of a plasma generating device, and performing the plasma sterilization under the condition of a high voltage electric field.
